Oxytocin pretreatment attenuates oxytocin-induced contractions in human myometrium in vitro.
BACKGROUND Oxytocin receptor desensitization has been shown to occur in humans at biomolecular level and in isolated rat myometrium; however, its effect on human myometrial contractility has not been demonstrated. The objective of this in vitro study was to investigate the contractile response of human pregnant myometrium to oxytocin after pretreatment with different concentrations of oxytocin ...
متن کاملImmunocytochemical evidence for PDBu-induced activation of RhoA/ROCK in human internal anal sphincter smooth muscle cells.
Studies were performed to determine the unknown status of PKC and RhoA/ROCK in the phorbol 12,13-dibutyrate (PDBu)-stimulated state in the human internal anal sphincter (IAS) smooth muscle cells (SMCs). We determined the effects of PDBu (10(-7) M), the PKC activator, on PKCα and RhoA and ROCK II translocation in the human IAS SMCs. We used immunocytochemistry and fluorescence microcopy in the b...
متن کاملHyperglycemia- Induced NF-κB Activation Increases microRNA-146a Expression in Human Umbilical Vein Endothelial Cells
Background & objectives: Nuclear Factor kappa B (NF-κB), a master switch transcription factor, plays a critical role in the progression and development of hyperglycemia-induced microangiopathy. Hyperglycemia activates NF-κB, and subsequently increases pro-inflammatory cytokines such as TNF-α, IL-6 and IL-1β leading to development of inflammation. Some new studies have revealed the involvement o...

15 صفحه اولGhrelin in the human myometrium
BACKGROUND Ghrelin is a 28-amino acid octanolyated peptide, synthesised primarily in the stomach. It stimulates growth hormone release, food intake and exhibits many other diverse effects. Our group have previously determined that ghrelin inhibited human contractility in vitro. The aim of this study therefore, was to investigate the expression of ghrelin, its receptor, the growth hormone secret...
